Duarte, CaliforniaAges 18 years+ - NCT07077239Recruiting
Adaptive radiation after prostate surgery to lower side effects
This trial tests a precise, short-course radiation treatment (stereotactic body radiotherapy) after prostate removal surgery that adapts to your body each day to reduce side effects. It is for people whose prostate cancer has high-risk features or a rising PSA after surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT07244341RecruitingPhase 1
Valemetostat and darolutamide for advanced prostate cancer
This trial tests a new combination of two drugs (valemetostat and darolutamide) for men with metastatic castration-resistant prostate cancer that has worsened after prior treatment. The goal is to see if the combination can slow cancer growth.
La Jolla, CaliforniaAges 18 years+ - NCT06842498RecruitingPhase 2
FG-3246 for advanced prostate cancer
This trial tests a new drug called FG-3246, which targets a protein (CD46) on prostate cancer cells. It's for men with advanced prostate cancer that has spread and stopped responding to standard hormone therapy, and who have had limited prior treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT06615752RecruitingPhase 1/Phase 2
Green tea and quercetin with chemo for prostate cancer
This trial tests whether adding green tea extract and quercetin (a plant compound) to standard chemotherapy (docetaxel) can help men with advanced prostate cancer that has stopped responding to hormone therapy. The goal is to see if this combination is safe and works better than chemo alone.
Los Angeles, CaliforniaAges 18 years+ - NCT06545942RecruitingPhase 1
Studying MOMA-313 for advanced or metastatic solid tumors
This trial tests a new oral drug, MOMA-313, alone or with another drug (olaparib), in people whose cancer has a specific DNA repair problem (HR-deficient mutation). It aims to see if the drug can shrink tumors or slow their growth.
La Jolla, CaliforniaAges 18 years+ - NCT06580002RecruitingPhase 2
Can Riluzole Help with Chemo Brain? A Pilot Study
This study tests if a medicine called riluzole (currently used for ALS) can help with 'chemo brain' – memory and thinking problems after cancer treatment. It is for people who feel their mental sharpness has declined after breast cancer therapy, certain chemotherapies, or brain radiation.
Orange, CaliforniaAges 18 years+ - NCT07690306Enrolling by invitation
AI study to improve prostate cancer diagnosis with MRI and PSMA PET scans
This study is testing whether artificial intelligence can better predict prostate cancer by combining two types of scans (MRI and PSMA PET) along with your medical history, PSA, and biopsy results. If you have already had these scans and a biopsy, your information may help researchers develop a more accurate, non-invasive diagnostic tool.
Los Angeles, CaliforniaAges 18 years+ - NCT07611110RecruitingPhase 3
AZD2265 vs standard care for advanced prostate cancer
This trial tests a new cancer-fighting drug called AZD2265 against standard treatment for men with advanced prostate cancer that has spread and stopped responding to hormone therapy. You may qualify if your cancer previously responded to PSMA-targeted radiation treatments but is now growing again.
Irvine, CaliforniaAges 18 years+ - NCT05882253Recruiting
Test MRI-guided biopsy for early prostate cancer detection
This study uses a special MRI-guided (MRI-fusion) needle biopsy to look for early prostate cancer. It may help find concerning areas more accurately before cancer spreads.
La Jolla, CaliforniaAges Any age - NCT05593497RecruitingPhase 2
Combination therapy before prostate surgery for high-risk prostate cancer
This study tests a combination of hormone therapy and a targeted drug before prostate surgery for men with high-risk prostate cancer that has not spread. The goal is to see if this approach can improve outcomes.
West Los Angeles, CaliforniaAges 18 years+ - NCT07569926RecruitingPhase 4
Fluciclovine PET scan for prostate cancer recurrence detection
This study tests whether a newer type of imaging scan (called fluciclovine PET) can find where prostate cancer has come back when an earlier scan (PSMA PET) didn't show clear results. The goal is to help doctors better plan treatment for men whose cancer has returned after surgery or radiation.
San Diego, CaliforniaAges 18 years+ - NCT03972657RecruitingPhase 1/Phase 2
Testing a new prostate and kidney cancer drug with immunotherapy

What taking part in a prostate cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
